The present study was conducted to examine the differences and correlations between verbal fluency and story comprehension according to the working memory(WM) capacity, and to find out what WM factors influence the linguistic competence in Alzheimer's disease(AD) and vascular dementia(VaD) groups each consisting of 15 patients. The results of their performance produced firstly significant differences in phonemic fluency, story comprehension, delayed recall and recognition task between the two groups. Further analysis shows that VaD group had significant correlations between the scores of story comprehension and the recognition test scores additionally. These findings suggest that it is possible to differentiate the two groups even by story comprehension tasks and WM. In conclusion, the clinical application of the results is likely to contribute to appropriate treatment plans and effective interventions for elderly with AD and VaD as well as to improve the classification criteria for both types of dementia.

This research reviewed the instrumental ADL for patients with mild cognitive impairment, which is one of the most interested topics, and hope that this research helps evaluating and treating the mid cognitive impairment patients in occupational therapy. The treatment for dementia patients are actively in progress, but there has not been treatment approach about mild cognitive impairment patients, who are in risk of moving on to dementia. In this review, we have dealt with the foundation of matching the point to instrumental ADL from the occupational areas of mild cognitive impairment patients and normal elders. We have discussed the that essential consideration about instrumental ADL is needed to prevent mild cognitive impairment developing into dementia. In conclusion, there is a need of regular evaluation about instrumental ADL considering the occupational areas of mild cognitive impairment patient groups, who are highly in risk of developing into dementia, and occupational therapeutic approach is needed as well.

This study was conducted to examine the relationships between nursing students' knowledge on dementia, care performance, and empathy, thus providing the foundation of dementia patient nursing intervention strategies for nursing students. For the analysis to examine the relationships, this study used descriptive statistics, t-test, ANOVA, Scheffé test, and Pearson's correlation coefficient. The analysis showed that the higher students' year of study and the higher their interest in dementia (F=5.02, p=.008), the higher their knowledge on dementia (t=-4.03, p<.001), and also that the higher their satisfaction with clinical training (F=3.91, p=.023), the higher their care performance. It was found that nursing students' knowledge on dementia and their care performance (r=.21, p=.023) were positively correlated at a statistically significant level. Based on the results, this study suggests the need to develop and utilize education programs that can help students gain knowledge on dementia prior to clinical training so that they can have more knowledge on dementia and be encouraged to practice caring for patients with dementia.

As the aging society continues in recent years, interest in dementia is increasing. Among them, Alzheimer's disease is a degenerative brain disease that accounts for the largest percentage of all dementia patients, with the medical community currently not offering clear prevention and treatment for Alzheimer's disease, and the importance of early treatment and early prevention is emphasized. In this paper, we intend to find the most efficient activation function by combining various activation functions centering on convolutional neural networks using MRI datasets of normal people and patients with Alzheimer's disease. In addition, it is intended to be used as a dementia classification modeling suitable for the medical field in the future through Alzheimer's dementia classification modeling.

Objective : The purpose of this study was to examine the effect of group occupational therapy including education regarding depression, anxiety, and activity participation in people with dementia. Methods : Nineteen people with dementia were randomly assigned to experimental(n=10) and control group(n=9). The participants in experimental group conducted occupational therapy including education, whereas the control group occupational therapy only. Pre- and post- assessments were applied using Korean form of Geriatric Depression Scale(K-GDS), Hamilton Anxiety Scale(HAM-A), State Trait Anxiety Inventory(STAI-X-1), and Korean Activity Card Sort (K-ACS). Results : When comparing the differences between pre- and post- of the intervention, the depression and anxiety of occupational therapy group including the educational program decreased statistically(p<.05). Conclusion : This study has shown that occupational therapy including education has significant effects on reducing depression and anxiety in people with dementia. In the future, it will be necessary to develop an intervention program to strengthen the psychological and emotional aspects of people with dementia, and various studies in the field of occupational therapy focusing on care giver education should be conducted.

The purpose of this study was to evaluate the status of oral health care in dementia patients living in long-term care facilities and to investigate the effects of this on swallowing function and swallowing-quality of life. The subjects were 60 demented patients who were admitted to long-term care facilities in Gwangju and Jeonnam provinces. Their Oral Health Assessment Tool(OHAT), Clinical Dysphagia Scale(CDS), and Oral Health Impact Profile 14(OHIP-14) were measured. The results of this study were as follows: First, the effect of oral health care on dentition patients using long-term care facilities on swallowing function and swallowing-quality of life was significantly different according to oral care score (p<.05)(p<.01). Second, the relationship between oral health care and swallowing function of dementia patients and swallowing-quality of life. was examined. As a result, oral health care of dementia patients was affected by swallowing function (r=.405, p<.01) the swallowing-quality of life (r=.462, p<.01) and swallowing function were significantly correlated with swallowing-quality of life (r=.351, p<.01). Therefore, the oral health care of users of long-term care facilities was closely related to swallowing function and swallowing-quality of life.

The purpose of this study was to investigate how self-help group conducted by 25 dementia safety centers in Seoul correlated the stress and life satisfaction of primary care-givers of dementia patients. At 25 dementia safety centers, self-help groups were identified, and a survey was conducted for the care-givers of dementia patients participating in the self-help groups. SPSS 21.0 program was used for the collected data, and reliability was analyzed for stress level and satisfaction after the program. Multivariance analysis and one-way analysis were performed for the types of self-help groups, the frequency of attendance, and the number of meetings. The result were : first, the total stress felt by participants was close to 4 out of 5, and there was no significant difference in meeting type and attendance frequency, and only in the relationship between stress and the number of self-help groups(p<.05). Second, the satisfaction after self-help meetings was close to 4 out of 5, the meeting type and attendance frequency no significant difference, and only the number of self-help meetings showed a significant difference(p<.05). Third, there was a significant negative correlation in the relationship between stress and program satisfaction. As can be seen from the results, it can be seen that self-help groups have an effect on the stress of primary care-givers and the satisfaction level after meeting.

Purpose: To investigate the relationship between dementia and complete tooth loss on both sides or one side using large demographic data. Materials and methods: A retrospective cohort study was designed using the National Health Insurance Service-Elderly Cohort Database (NHIS-ECD) which was established for people over the age of 60. The experimental group was the complete edentulous cohort, which had a history of treatment for national health insurance covered complete denture on both sides or one side from July 1, 2012 to December 31, 2013. And the control group was the dentulous cohort, which had a history of conservative dental treatment for the same period. All subjects had no history of diagnosis or treatment of dementia during this time. These cohorts were matched 1:1 by age, gender, and place of residence according to the propensity score matching method. Then the incidence of dementia was compared between these cohorts. Results: Compared with those groups, the incidence of dementia was significantly higher in the experimental group (12.13%) than in the control group (9.74%) (P<.05). No clear association between other factors has been identified. Conclusion: The analysis of large-scale demographic data shows that the incidence of dementia is high in complete edentulous patients on both sides or one side.
